What if the future of aviation didn’t rely on heavy lithium-ion batteries or complex hydrogen systems, but instead on a fuel as simple and abundant as sodium? At MIT, researchers are turning this bold ...

Hydrogen fuel cells, which power some electric cars, pack far more energy per weight than lithium-ion batteries. The devices also show promise for decarbonizing aviation, shipping, and trucking. But ...

Fuel cells powered with the metal could provide a new source of electric power that's far more energy-dense than lithium-ion batteries. A new type of fuel cell that runs on sodium metal could one day ...
